Vestibular disorders: Causes, symptoms and management

Vestibular disorders affect the inner ear and brain, leading to dizziness, balance problems and other symptoms that can impact daily life. These conditions range from benign paroxysmal positional vertigo (BPPV) to more complex issues like Ménière’s disease and vestibular neuritis. Understanding the causes, symptoms and treatment options can help those affected manage their condition effectively.

What causes vestibular disorders?

Vestibular disorders can result from various factors, including:

• Inner ear infections or inflammation – Conditions like vestibular neuritis or labyrinthitis can cause dizziness and balance issues.
• Ménière’s disease – A disorder linked to fluid buildup in the inner ear, leading to vertigo, hearing loss and tinnitus.
• Benign paroxysmal positional vertigo (BPPV) – Small calcium particles in the inner ear become displaced, causing short episodes of vertigo.
• Head injuries – Trauma can damage the vestibular system, leading to dizziness and imbalance.
• Age-related degeneration – The vestibular system may weaken over time, increasing the risk of dizziness and falls.
• Neurological conditions – Disorders such as migraines or multiple sclerosis can affect balance and spatial orientation.

What are the symptoms of vestibular disorders?

The symptoms of vestibular disorders vary depending on the underlying cause but commonly include:

• Dizziness or vertigo – A sensation of spinning or unsteadiness.
• Balance problems – Difficulty walking straight or feeling off-balance.
• Nausea and vomiting – Common with severe vertigo episodes.
• Hearing changes – Some conditions may cause hearing loss or tinnitus.
• Blurred vision – Difficulty focusing, especially during movement.
• Cognitive difficulties – Issues with concentration or memory due to prolonged dizziness.

How are vestibular disorders diagnosed?

A GP or specialist may use various tests to diagnose vestibular disorders, including:

• Physical examination – Checking eye movements, balance and coordination.
• Hearing tests – Assessing any hearing loss linked to inner ear problems.
• Videonystagmography (VNG) – Measuring involuntary eye movements to detect balance issues.
• MRI or CT scans – Imaging tests to rule out neurological causes.
• Vestibular evoked myogenic potentials (VEMP) – Evaluating inner ear function.

How are vestibular disorders managed?

Treatment for vestibular disorders varies depending on the cause. Vestibular rehabilitation therapy (VRT) is a common approach, involving exercises that help improve balance, reduce dizziness and retrain the brain to compensate for vestibular dysfunction. Medication may also be prescribed, including anti-vertigo drugs, anti-nausea medication or corticosteroids to reduce inflammation.

Lifestyle adjustments can play an important role in symptom management. Avoiding triggers such as bright lights, sudden movements and dehydration may help reduce dizziness. Additionally, dietary changes, such as reducing salt intake for Ménière’s disease or maintaining stable blood sugar levels, can improve overall vestibular health.

In some cases, surgical intervention may be necessary, particularly for severe or persistent conditions. Procedures such as endolymphatic sac decompression or vestibular nerve section may be considered if other treatments have not been effective.
